Got some toy caps from cabelas. Parris brand. Tried them on my NAA companion. Plactic strips of caps that are in strips. Trimmed them off with a nipper into singles. Not strong enough to ignite but enough oomph to send powder out the barrel upon further examination on this particular gun the nipples are screwed in by a hex wrench. It leaves enough room to trickle powder into the nipple and the caps press on flush. Gives it just a little more bite to set the charge off. Yes it will work and it,s a PITA for sure but again it keeps things going without taxing your cap supply. Am I cucco for cocao puffs or just too much time on my hands,,,,,suggestions welcome....
